Gather profile metrics

[chuckwondo]

• Write function timings to output file because Scalene does not capture elapsed times for functions, sadly
• Generate simple profile combining function elapsed times with some Scalene metrics
• Add script to compute mean of simplified profiles
• Add NASA scripts for batching jobs
• Split DPS vs ADE/dev build scripts to eliminate the need to specify a --dev option for ADE/dev environments
• Correct NASA installation instructions
• Add esa output subdir to README instructions
• Add NASA- and ESA-specific instructions for locally running the algorithm to emulate the respective systems.
